REVUE BRYOLOGIQUE 35 



(Iraregion. From Dudinka we went by steamboat still farther 

 to the north, or to Malo-Briochowskij island (about 70" 40' n. 

 latitude), one of the most northerly islands of the archipi- 

 lago in the mouth of the Jenisei. Here, and after the 25th of 

 August a little in south of the archipilago, we vainly waited 

 that the seaparty of the expedition should arrive to carry us 

 home. On the 4lh of September we finally received intelli- 

 gence by a messenger that Professor Nordenskjoeld had been 

 at the mouth of the river, but had been obliged to return 

 without us, lest the ice should set in at so late a season of 

 year. Through a miraculous coincidence of obstacles both 

 the parties had been hindered to join. Consequently it was 

 nothing left to us but to return the same toilsome way we 

 had come ; by these means we, however, gained an unex- 

 pected occasion to pursue our explorations of the flora and 

 fauna of the nether Jenisei much longer than was before 

 calculated. We returned slowly by steamboat up the river 

 to Jeniseisk, whither we arrived on the 4th of October. In 

 Jeniseisk we still continued our excursions till the snow put 

 and end to all further herborizing. Our rich collections hav- 

 ing been packed up, we left Jeniseisk on the 2-2d of October 

 and, journeying on as swiftly as possible, came back to 

 Stockholm on the 9th of December. 



From what is here above mentioned it appears that we 

 could devote nearlv 5 months to the exploration of the valley 

 of the nether Jenfsei. In this time we visited about 60 dif- 

 ferent places by the river. As, however, we had to travel! 

 down and up the river, the long way of about 15 degrees of 

 latitude, in a contry where the communications are, as yet, 

 very bad in only one summer, we had, of course, no lime 

 to remove far from the river ; all our excursions accordingly 

 being limited to the very valley of the nether Jenisei. 



It was already aforehand to be supposed that the moss vegeta- 

 tion of the nether Jenisei should not be very rich in species, be- 

 cause thelandcape at this partof the riveris very monotonous, 

 not affording the same rich variety of situation that we arc 

 accustomed to in most of the eastern parts of Europe, I do 

 not however overrate my collections from the Jenisei in ap- 

 preciating them to at least 300 species. The greatest part of 

 these mosses are. of course, natives also of the Scandinavian 

 ■ peninsula, which country, among all the different contries 

 of eastern Europe, is most naturally set up as a point of 

 comparison, as it is situated under the same degrees of la- 

 titude as the now explored region by the nether Jenisei. 

 There are, however, also a good deal of mosses by the Je 

 nisei that are not natives of Scandinavia, and many of the 

 last-mentioned mosses, moreover, will certainly prove to be, 

 as vet, undescribed. The differences in this respect between
